Embodiment approach

[0067] Next, an example of the following embodiments of the present invention will be described. In this embodiment, a method of manufacturing a printed wiring board having through holes will be described with reference to the drawings.

[0068] In the manufacturing method of the printed wiring board of the present embodiment, first, as Image 6 As shown, prepare the existing copper clad laminate 4 . Next, since in this embodiment mode is formed as Figure 14 The steps before the shown through-hole 17 are the same as the conventional steps, and therefore description thereof will be omitted.

[0069] Such as Figure 14 As shown, it is assumed that the via hole 17 is formed through a via hole forming step.

[0070] Such as figure 1 As shown, in this embodiment, the etching step is provided before or after the via hole forming step. In this etching step, copper foil 15 is removed by etching. Then, in the degreasing process, the whole is degreased. Thus, if Figure 5 As s...

Abstract

A method of manufacturing a printed wiring board, according to which a printed wiring board can be obtained quickly and easily, the manufacturing method comprising a degreasing process of degreasing a substrate part, on the substrate part degreased by the degreasing process, and equivalent A step of irradiating ultraviolet rays to a portion where the conductor pattern is not formed, a catalyst attaching step of attaching a catalyst to the substrate portion after ultraviolet irradiation, and a plating step of performing plating on the substrate portion on which the catalyst is attached in the catalyst attaching step .

Description

technical field [0001] The present invention relates to a method of manufacturing a printed wiring board mounted with various electronic components. Background technique [0002] Various printed wiring boards mounted with various electronic components and installed in electronic equipment have been used conventionally (for example, refer to Patent Document 1). [0003] Among these printed wiring boards, a printed wiring board having through holes is generally manufactured through the following steps. [0004] First, if Image 6 As shown, a copper clad laminate 4 in which copper foil 3 is provided on both main surfaces of a substrate portion (substrate body) 2 made of epoxy resin or the like is prepared. Then, if Figure 7 As shown, a thin film 8 is provided on both surfaces of the copper foil 3 . [0005] further, such as Figure 8 As shown, a pattern film 9 for forming a conductor pattern is provided on both surfaces of the film 8 . Then, in an exposure step, ultraviol...
